INTEGRATED EPR NMR WITH FREQUENCY AGILE GYROTRON

摘要

A frequency agile gyrotron for use in combination with an NMR system is disclosed. The frequency agile gyrotron combined with EPR-NMR magic angle spinning resonators and cryogenic sample cooling may increase the sensitivity of solid state NMR with DNP.

主权项

1. A frequency agile gyrotron system for DNP NMR comprising:
an NMR spectrometer; a signal processor operatively connected to the NMR spectrometer, wherein the signal processor receives one or more voltages from the NMR spectrometer and produces a control signal; and a frequency agile gyrotron operatively coupled to the NMR spectrometer and to the signal processor, the frequency agile gyrotron configured to emit a broad-banded microwave output comprising a gyrotron bandwidth; wherein:
the NMR spectrometer controls a frequency of the broad-banded microwave output via the control signal,the frequency agile gyrotron responds to the control signal on a timescale of microseconds, andthe gyrotron bandwidth is wider than an EPR linewidth and an NMR frequency.
